James Van Allen
Not many people can say that they outlived their obituary writer. However, in the case of physicist James Van Allen (1914-2006), he outlived his obituary writer by ten years.
In 1996, science reporter Walter Sullivan (1918-1996) was tasked by the Associated Press to write an obituary of Van Allen to be published once he passed away. At the time, Van Allen was already rather old so somebody in the Associated Press may have thought that his death was near.
The prewritten obituary was proven to be unnecessary since Van Allen lived for ten more years. He died on August 9, 2006, at 91.
In an ironic twist of fate, Sullivan died in the same year when he wrote Van Allen’s obituary.
